I checked out some 10x and 12x today for the first time and I agree those 12s are difficult even with the rest, at least from the standing position. The store was out of stock of 8s so I want to find a pair of those to check out before pulling the trigger. Are you able to glass a decent distance with the 8s or is the max effective range a lot closer in?
It really depends on the scenario, on an antelope hunt last fall I could glass up goats 2-3 miles away and couldn’t even see them with my spotter from the heat waves. You can see a lot all the way to the edge of the huge FOV so you can pick up more on a tripod over a lot of 10’s. I will not go back to 10’s, I love my 8’s and I’m using 8x32’s.
As far as effective range when I’m shed hunting there are times when i need the 14’s to find a tine vs the 8’s due to the size and distance. I’ve also found way more with the 14’s and 8’s than a spotter due to the small FOV. Overall I love the 8’s, if I could only have one piece of glass I would get rid of everthing except my 8’s.
